I am getting ready to install KOa and was wondering if anyone can give me advice that has worked with this wood. I would like to know the size and type of fasteners to use on this product. It will be layed over a 3/4" plywood floor the Koa is 3 1/4" wide 3/4 in thick.

Tongue splitting is an issue. You have to play around with air pressures and foot plate angles initially. I use 15 ga. staples. No need to pre drill.

This floor changers color dramatically right off the bat... don't put any rugs down until after 6 months.
